Table 7 Results of multiple regression analysis showing factors independently associated with longer scene times in physician treated patients

From: Prehospital response model and time to CT scan in blunt trauma patients; an exploratory analysis of data from the head injury retrieval trial

Parameter Mean additional scene time in minutes (95% CI) P value
Pelvic compression device (compared to none) 11 (3–19) 0.008
Thoracic decompression (compared to none) 24 (11–36) <0.001
GSA HEMS treatment (compared to HIRT HEMS) 13 (7–18) <0.001
Entrapment when physician team present (compared to no entrapment when physician team present) 19 (14–23) <0.001
